I think Eric and I said exactly the same thing, but my explanation was looking
into the radio while Eric's was looking at the business end of the cable.
I would NOT recommend any RIB-less cable. Most are powered by the serial port,
and some RSS programs don't activate the proper handshaking

I tossed it. I was looking for a preselector for a repeater project. No big

Oh heavens no. It's a sin to have GE equipment sitting around unused.
Someone should have been strung up for letting that repeater sit in a box
all that time.

I'll ask, even though I have not fully researched the BatLabs cable before

Is the BatLabs cable meant to be used with a RIB or by itself? (I know some

Yes, the cable shown on Batlabs must be used with the Motorola RIB. The
pinout on the RIB end may not match boxes made by other vendors such as
Polaris. The jumper you see on the RIB end establishes a bias voltage on
the SCI (Bus +) line, and some aftermarket RIB clones do not use
I'm not running any MVP's in duplex - they are in service as either link
radios or monitor receivers. However, I've used Exec II's without backing
them down much (reduced due to heat considerations).

I have built many MVP repeaters using the NHRC MVP controller. I always
test the repeater with full output power. I have never witnessed any in

Hi all
I am looking for someone that may have modified a Decibel four bay
folded dipole antenna to operate in the UHF hamband. I'm not sure if
the one I have is 450-470 or the lower UHF 420 type there is no tag on
this one.
Thanks in advance
Mike
Mike , I had a Similar Question My is made By DB But had a Mot Tag on
it , I was told to just Try it and check the Swr it was about a 1.8
So the advice I got was to just use it and I did and it works Fine , it
is a Very Well made ant .
Answers still should be in the files
Good Luck
What is the length of one of the dipole loops from top of the bottom? Measure
straight across each
arc from inside edge of one to the outside edge of another or, give
center-to-center measurement.
Also measure the length of the pigtail on that same loop to the center of the
molded Y splitter.
The overall length of one element for 450-470 MHz should be about 11-3/16
The overall length of one element for 406-420 MHz should be about 12-1/2

The person asking the question didn't know the frequency range of his
antenna. The lengths I gave him will tell him that. That's all I was doing.
If it's the 450-470 model, it will work as-is. If it's the 406-420 model,
he's probably out of luck. Changing the harness lengths will be almost

Let's not forget that the MVP repeater in question is the LPI (Low Power
